Yeah, the only difference from the higher than baseline *Sync from either is that the higher tiers support higher refresh rates and HDR certification. Gsync goes a few bits beyond that with Ultimate requiring a display to have a minimum support like 1000 nits etc.
FreeSync | FreeSync Premium | FreeSync Premium Pro (renamed to FreeSync 2 later) |
|---|---|---|
Tear-free | At least 120Hz at FHD resolution | HDR support |
Low flicker | Low framerate compensation (LFC) | At least 120Hz at FHD resolution |
Low latency | Tear-free | Low framerate compensation (LFC) |
| Low flicker | Tear-free |
| Low latency in SDR | Low flicker |
| | Low latency in SDR and HDR |
| G-Sync | G-Sync Ultimate | G-Sync Compatible |
|---|---|---|
| Validated for artifact-free performance | Validated for artifact-free performance | Validated for artifact-free performance |
| Certified with over 300 tests | Certified with over 300 tests | |
| Certified for 1,000 nits brightness with HDR |
SAM does seem to work on a lot more titles
SAM also can have a far greater negative impact based on its tendency to put more load on the CPU too going by posts on reddit in the AMD subs. ReBAR is more conservative, Nvidia whitelist more games here and there but you can easily enable it for every game using Profile Inspector and it might yield a few more fps, it might not, but typically losing fps is not a thing when force enabling ReBAR.
Back on topic with RTX though, this is specifically RTX related as it involves Ray Reconstruction and how it handles shadows and finite details that would otherwise be missing in standard ray and path tracing. Some of these details are there in raster because these things are baked into the traditional probing of the scene, but can be lost with RT/PT due to the nature of denoising losing some of those details, and RR bringing them back whilst cleaning up denoising in the process.
I picked this scene by accident as I was walking past it on the way to a missiiong and noticed the strong green casting all over the place, a perfect scene to use to demonstrate Raster vs RT vs PT and Ray Reconstruction's benefits:

Pay special attention to the shadow of the tree on the ground. In raster they are blocky/messy and the motion is messy too.

I don’t honestly see a difference mate. 9/10 people would probably not even notice.SAM also can have a far greater negative impact based on its tendency to put more load on the CPU too going by posts on reddit in the AMD subs.

Can't be serious surely?
You telling me that difference is not worth dropping £1500+ on a GPU for?
I can see the light bounce off the green wall on to the building and floor, that's Global illumination, but you don't need RT to do that, you can do that in screen space.
To me it looks over saturated, it looks overdone to showcase it.
GI in Cyengine 3.8, 2019, no Ray Tracing here, you can see the effect all around but pay attention to the box in the middle foreground.
this makes almost no difference to performance.

Yeah much of this can be done in screen space and it looks great, The Last of Us for example uses it to great effect as does Uncharted 4 series. But these are manual labour intensive tasks requiring someone to one by one apply those into the scene - The whole point of RTGI/RTDI etc is that a developer can just apply material properties to the scene then slap in the sources of light and let ray tracing do the rest which cuts down a shed load of labour time which means they can then hopefully spend the saved time on polishing the rest of the game (or we would hope).
Checkout the lighting in this, again no RT, tho this game is getting RT.
2020 or 2021, can't remember exactly, but its an example of good lighting artists being good lighting artists and not just checking a radio button.

You might actually recognise it from my sig video, yes the state and lighting changes between day and night cycles.

Introducing the latest updates to StarEngine: The innovative suite of tools and technologies breathing life into Star Citizen and Squadron 42. --------------...

Is that why the game has taken like 12+ years to finally see a release horizon, because the artists are painstakingly tapping away with manually applying lighting
CIG started with 12 people in 2012 in a residential house, desk's crammed in bedrooms and hallways, you name it....
To now employing 1400 people in 5 studios around the world.
The technology needed to make the game didn't exist, so the invented it, they are still inventing it, for example server meshing where it is truly across one shared, you can not only see across servers but also affect across servers, shoot and kill people across servers, a game development first, and those servers span across billion's of KM, no boundaries, no load screens.
They have built a company from nothing, invented a lot of new tech from nothing, they are also making 2 games, Star Citizen, the MMO and the single player campaign Squadron 42. That's why its taken them 12 years and so far 750 million $.

They will implement ray tracing, too.Is that why the game has taken like 12+ years to finally see a release horizon, because the artists are painstakingly tapping away with manually applying lighting
I saw a video way back from CIG about a dev building a scene up, lit it up. Took a lot of time to get it right while it would have been right from the beginning with RT. Akin to a scene 4A (guys behind Metro), demoed with their engine where it showed how much time you save versus manually trying to fake everything with raster.

I wish PhysX had the same push RTX has had.
I found that made a bigger difference to games if I’m honest. In a lot of games the environment is static, you could fire a rocket launcher at a wooden crate and it’s still in one piece.
Borderlands 2 was great at the time, and I loved destruction in the earlier battlefield games (yes I know it’s not physX).
I really wish devs focused more on destructible environments and better A.I…

Ray/path tracing when used more often will hopefully allow devs to bring back more destruction since lighting/shadows, gi etc. won't be such a pain in the ass to accommodate.
Yes, that is the Standalone campaign mode of Star Citizen, and yes that is Mark Hamill.
Yes that is Jillian Anderson... yes that's a whole bunch of other actors you may recognise.
